World Record Freediver, Business Psychologist & Performance Expert
Ant Williams is a business psychologist and world record-holding freediver who combines academic expertise with elite athletic experience to teach leaders the mental skills required for peak performance. He holds the Guinness World Record for the deepest dive under ice on a single breath — 70.3 metres, set in a frozen fjord at Kirkenes, Norway, in March 2019 — has held his breath for over eight minutes, dived to 100 metres on a single breath, and swum 182 metres beneath solid ice. He was ranked world number three for five years in one of the toughest disciplines of the sport.
What makes Ant's story unusual is its origin. He spent years as a sport psychologist coaching elite athletes — MotoGP riders, big wave surfers, rock climbers, Olympians and Super Rugby teams — before deciding to test firsthand the principles he had been prescribing. That decision led to world records, an immersive film with Apple built around his 182-metre under-ice swim, and a complete reimagining of what he knew about risk, resilience and the limits of human performance.
Ant's keynotes combine gripping storytelling, techniques from applied sport psychology and immersive interactive experiences. For two decades he has studied the psychology of human performance, and his talks help leaders and teams excel under pressure, embrace uncertainty and develop the performance mindset required in environments where the stakes are genuinely high. He suits conferences, leadership summits and team events looking for a keynote with a physical edge.

What happens when a high-performing team, built for success, completely unravels under pressure?
Business leaders may not face the Arctic cold, but they do face relentless change, the challenge of shaping culture, and the pressure of leading others through uncertainty. In 2019, Ant Williams set out to break an extreme sport world record — becoming the deepest man under ice. Yet, within 24 hours of arriving in the Arctic Circle, his elite dive team fell apart. Heated arguments, poor communication, and a weakness for Vodka descended some team members into chaos.
In this dynamic and interactive keynote, Ant takes leaders inside this high-pressure mission to uncover the real reasons teams succeed or fail. Through vivid storytelling and an immersive problem-solving challenge, attendees will step into the shoes of his dive team, identifying critical decisions that could have turned the team around before disaster struck.
